20. Trade and other receivables

Trade and other receivables are recognised initially at fair value plus any directly attributable transaction costs. Subsequent to initial recognition they are measured at amortised cost using the effective interest method less any impairment losses.

A contract asset is recognised when the Group has a right to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditioned on something other than the passage of time. It is recognised as the revenue recognised minus the invoiced amount.

When the invoiced amount exceeds the amount of revenue recognised, the balance is classified as amount due to customer.

For trade receivables and contract assets, the Group applies a simplified approach in calculating ECLs. Therefore, the Group does not track changes in credit risk, but instead recognises a loss allowance based on lifetime ECLs at each reporting date. The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

The concentration of credit risk with respect to trade receivables is limited, as the Group’s customer base is large and geographically spread. As at 31 December 2025 a part of the trade receivables amounting to €36 million (2024: €30 million) is past due over one year but partly impaired. These overdue receivables relate to a number of customers and remain outstanding mainly due to ongoing discussions about claims and/or variation orders.

Retentions relate to amounts retained by customers on progress billings. In the United Kingdom and Ireland in particular, it is common practice to retain a percentage of invoiced amounts until completion of the project. Amounts due from related parties mainly comprise receivables from joint ventures and associates. Other receivables include €13.6 million for the Group’s entitlement to old receivables of BAM Deutschland AG (2024: €13.6 million).

Provision for impairment of receivables in 2025 and 2024 is mainly related to disputed balances and final negotiations on these balances with the customers. No significant credit losses were incurred. Additions to and releases of provisions for impaired receivables are included in other operating expenses in the income statement.
